Question

How do I graph the function

Answer 1

Solve for f(x) by replacing x in the equation with a few different whole numbers until you get 4 or 5 sets of coordinates, then plot the coordinates on the graph.

When X = 0, you get f(0) = -0^2 +2(0) -5 = -5

So your fist set of coordinates is (0,-5)

Now replace x with 1: f(1) = -1^2 + 2(1) -5 = -4

Second set of coordinates (1,-4)

Replace x with -1: f(-1) = -(-1)^2 +2(-1) -5 = -8

3rd set of coordinates (-1,-8)

I used -1, 0, 1, 2, 3 to find 5 points for the attached graph

Answer 2

-1 / -8

0 / -5

1 / -4

2 / -5

3 / -8

this is where they would go on the graph
